The Vikings suffered several injuries in their preseason game against the San Diego Chargers on Friday night, Aug. 24, though it's unclear if any will be serious.

The biggest health question involves starting safety Mistral Raymond, who did not play because of lower back tightness in pregame warmups. Coach Leslie Frazier said he needs to find out more about the injury.

Raymond was one of three safeties to leave the Metrodome with injuries. Special-teams ace Eric Frampton and Andrew Sendejo have ankle sprains. So does cornerback Marcus Sherels, whose sprain could be high on the ankle.
